To fabricate removable partial denture which provide patient's comfort and maintain oral health, cast fabrication which reproduce anatomical and functional state of mouth is needed. Diagnostic cast and master cast are produced through the process of preliminary impression and final impression taking. Both of remaining teeth and edentulous area should be well taken in removable partial denture impression. According to the supporting type of partial denture, impression material and method can be changed. Therefore, understanding of impression procedure is essential for the accurate clinical application.

Physiologic tooth attrition is accepted as a natural change. But when pathologic changes, such as loss of occlusal vertical dimension, masticatory pain, loss of masticatory function, and loss of esthetics occur, restorative measures should be taken by dentist. A patient visited the clinic with the chief complaint of 'My lower teeth bite the palate and it hurts'. It was diagnosed as iatrogenic attrition of lower natural dentition caused by inappropriate upper restorations, resulting in traumatic overbite. Through model analysis and diagnostic wax up, increase in vertical dimension was decided. Upper and lower dentitions were restored with new prostheses. After restoration, satisfactory outcomes were achieved both in functional and esthetic aspects.

Objectives: Patients with excessive tooth wear should first be diagnosed for the etiology of the tooth wear. Causes of tooth wear include bruxism, clenching, and taking medications for systemic diseases. After identifying the cause of tooth attrition, the final prosthesis should be restored with an appropriate vertical dimension. Methods: A 79-year-old man with worn out teeth desired a whole dental treatment. He was on medications for high blood pressure and asthma. The treatment proceeded with a consultation with a medical doctor. The medications for asthma evoked multiple teeth wear and a loss of the vertical dimension. After recovery of 3 mm of vertical dimension, 2 months of evaluation was followed by an interim prosthesis. Results: The increased vertical dimension caused no problem in function and esthetics, and the final restoration was performed with a full monolithic zirconia crown. Group function, adequate anterior guidance, and the occlusal plane were determined. Conclusions: After the final restoration, the patient was both esthetically and functionally satisfied, and a night guard splint was delivered to prevent prosthesis fracture. The patient was informed about the potential tooth wear associated with asthma drugs and educated to visit the clinic regularly.

When the patient with class III malocclusion needs extensive oral rehabilitation due to multiple missing teeth, accurate diagnosis, and careful analysis, such as the patient's occlusal relationship, facial changes, and evaluation of the temporomandibular joint are essential. Orthognathic surgery is often performed for aesthetic improvement, depending on the patient's chief complaint. If it is not possible due to certain circumstances, partial aesthetic improvement can be achieved through minimal elevation of the vertical dimension. As this patient may have unexpected issues, such as temporomandibular joint disorder, oral habits like bruxism, and masticatory muscle tension, it was determined whether the patient could adjust to a reversible temporary removable partial denture. After this, the maxillary implant-supported fixed prostheses and the mandibular fixed prostheses were used to achieve stable posterior support and to partially improve the maxillary anterior esthetics. The patient was satisfied with the results both aesthetically and functionally. The prognosis is expected to be good if regular check-ups are conducted.

$T4K^{TM}$(Myofunctional Research Co, Australia) is one of the myofunctional appliance developed to be used in children of mixed dentition. Myofuncitonal appliance stimulate the facial, masticatory and tongue muscle and help to balance the muscular force. Labial bow included in the device exerts strength in excessively labial inclineded upper jaw, Lip bumper blocks strength of the mouth to prevent abnormal strength exerted in lower jaw, Tongue tag secures proper position of tongue, and additional exercise is not required for child patients. For the more, simpler design and softer texture of device prmoted cooperation of patients during use. This case report is to present the satisfactory results gained by using $T4K^{TM}$ on Class II patients. Comment 1. $T4K^{TM}$ was applied in Class II malocclusion patients of mixed dentition with expected space insufficient to gain facial improvement. 2. Excessive overjet, overbite were improved. 3. Main effects are regarded to have been achieved by development of lingual slant of upper jaw, labial slant of lower jaw, and lower part of jawbone. 4. Bad habits, such as mouth breathing, can also be adjusted.

For a full-mouth fixed prosthetic treatment of the edentulous patient, it is essential to confirm the proper tooth position and thorough evaluation of the remaining alveolar bone and soft tissue before surgery. CAD-CAM dentistry and guided implant surgery have such advantages of providing simultaneous planning of surgery and prosthetic treatment to ensure pre-knowledge of the treatment. In this clinical case, using the digital technology, digital temporary denture fabrication, esthetic evaluation before fixed prostheses treatment, and guided surgery planning was possible. After the surgery, previously obtained data was used for fabricating fixed temporary prostheses. Definitive zirconia prostheses transferred from the provisional prostheses were fabricated and functionally and esthetically satisfying results were obtained.

The gradual teeth wear with age is a natural phenomenon, but excessive wear beyond physiological levels can lead to vertical dimension loss, occlusal imbalance, temporomandibular joint disorders, and periodontal disease. In such cases, prosthodontic restoration becomes necessary emphasizing the importance of appropriate vertical dimension increase and stable occlusion in central relation (CR). In this case, a 74-year-old patient with clenching and grinding habit had severe teeth wear and after assessing interocclusal distance, wear degree, pronunciation, and facial profile, it was decided to perform full-mouth fixed prosthesis restoration with a 4 mm vertical dimension increase. And the significantly displaced Maximum Intercuspal Position (MICP) caused by parafunctional movements was re-established as a stable mutually protective occlusal relationship at centric relation and after a successful 4 months adaptation to provisional restorations, the final prosthesis was fabricated. During 4months of observation periods, stable occlusion in central relation and mutual protection occlusal relationships were maintained and the patient was satisfied with function and aesthetics, leading to this report.

In patients with unstable mandibular movements who are accompanied by involuntary facial muscle movements and asymmetrical changes in the facial features, many difficulties exist in determining the vertical dimension of occlusion, recording centric relation, and transferring information about the occlusal plane. In this case, for a patient with unilateral facial nerve palsy who was edentulous for a long period of time, a CAD-CAM provisional prosthesis was fabricated using a 3D printing customized gothic arch tracer and a prefabricated occlusal plane recorder, the POP bow system, to achieve a stable interarch relationship. Afterwards, a full mouth implant fixed prosthesis was fabricated by delivering an appropriate vertical dimension of occlusion, a reproducible centric relation, and a correct three-dimensional occlusal plane, and continuous maintenance was performed to restore functional and aesthetic oral health to the patient.

Anatomical changes in the facial and alveolar bones occur after multiple teeth are extracted. In the maxilla, the alveolar bone is absorbed in the direction and inclination of the root, and the remaining alveolar bone becomes shorter, reducing the diameter of the arch. In addition, as the nasolabial angle increases, the support of the lips and the aesthetics of the face are lost. This case reports a functional and aesthetically satisfactory results of full mouth rehabilitation with the implant-supported fixed prosthesis using a zirconia framework.
